Fire Ants, from Pitt T. Maner III
At age 3 in Tallahassee I learned the hard way that you can not to play in fire ant mounds. A very adaptable insect– millions of dollars have been spent to eradicate them.
"Fire ants roll 'snowballs' to dig a tunnel":
"The ants' ability to build their home in different types of soil could help explain their global expansion. In the past century, they have spread from their native South America to many other countries including the US, Australia and China. And they're not only comfortable on land: the insects can withstand water as well, by banding together to form unsinkable rafts the size of dinner plates that can handle waves and unforeseen forces."
